Here is the right Oops. -- Jan ksymoops 2.4.9 on x86_64 2.6.5-mm1. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.5-mm1/ (default) -m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed No modules in ksyms, skipping objects No ksyms, skipping lsmod Unable to handle kernel NULL pointer dereference at 0000000000000004 RIP: <ffffffff80269922>{cpufreq_frequency_table_cpuinfo+2}PML4 3e8f6067 PGD 3e963067 PMD 0 Oops: 0000 [1] PREEMPT CPU 0 Pid: 5201, comm: modprobe Not tainted 2.6.5-mm1 RIP: 0010:[<ffffffff80269922>] <ffffffff80269922>{cpufreq_frequency_table_cpuinfo+2} Using defaults from ksymoops -t elf64-x86-64 -a i386:x86-64 RSP: 0018:000001003ecb7d90 EFLAGS: 00010246 RAX: 00000000001e8480 RBX: 000000000000000c RCX: 0000000000000000 RDX: 00000000fffffffb RSI: 0000000000000000 RDI: 000001003fb739c0 RBP: 000001003f40f600 R08: 0000000000000033 R09: 0000000000000003 R10: 00000000ffffffff R11: 0000000000000000 R12: 000000000000020c R13: 000000000000000c R14: 00000100000f0e88 R15: 000001003fb739c0 FS: 0000003872f0f060(0000) GS:ffffffff803ef580(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000004 CR3: 0000000000101000 CR4: 00000000000006e0 Process modprobe (pid: 5201, stackpage=1003e8b5000) Stack: ffffffffa0003523 0000000000000002 ffffffff00000002 000001003fbc3c60 0000000000000001 000001003fb739c0 ffffffff803ba688 000001003fb739e8 0000000000000000 0000000000517c70 Call Trace:<ffffffffa0003523>{:powernow_k8:powernowk8_cpu_init+1315} <ffffffff802691e1>{cpufreq_add_dev+257} <ffffffff8013333e>{printk+494} <ffffffff80213a09>{sysdev_driver_register+121} <ffffffff802696fb>{cpufreq_register_driver+219} <ffffffffa0003698>{:powernow_k8:powernowk8_init+216} <ffffffff80149c8e>{sys_init_module+318} <ffffffff8010f172>{system_call+126} Code: 83 7e 04 fe 41 b8 ff ff ff ff 89 ca 74 22 31 c0 8b 44 c6 04
